TO ALL WHOM IT l\IAY CONOERN:

Be it known that I, MILTON ECKLEY, of the town of Olney, in the county of'Richland, and State of Illinois, have invented a new and improved Machine for Cleaning Grain; and I do hereby declare that the following is a full, clear, and exactl description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming pafrt of this specification, and in which- Figure 1 is a longitudinal sectional elevation in. the plane of the line rc, iig. 2, and partly broken away to show the riddle.

Figure 2 is a side elevation, partly in section. Similar letters of referencejndicate corresponding part-s in the drawings.' v This invention-relates to an improved machine forcleaning graiu,.and it consists inthc construction ofthe cylindrical screen, surrounded by wire gauze or netting of different degrees of neness,.one halfof their covering forming a chess-screen and the other a cockle-screen, said cylinder containing `spiral llange'surroun-ding the shaft; and in the arrangement of the riddle-fans and cylindrical screen, as will be hereinni'termore fully described. In the drawings, A represents the frame of the machine, composed of four or more uprights, secured together in the ordinary manner, hy horizontal pieces framed into them. B is the shaft, having its bearings in the lower cross-bars of the frame. To one end is attached thecrank by which the machiueis operated.V Upon this shaft is mounted the cylindrical screen, D, one end of which is provided, near its periphery, with a discharge-opening, a, shown in dotted lines fig. 2, and the other provided viith a central opening, through which the spout passes to vconduct the grain into said cylinder. The periphery ofthe cylinder is composed, one half of fine wire' netting or gauze, having square openings forming the cockle-screend, and the other of ooarser Wire netting or gauze, having rectangular openings, forming the chess-screen cZ, both of which are secured to the periphery of the ends ofcylinder by any suitable means. Y v

The length ofthe screen D, I prefer to make equal to its diameter, although this is not absolutely essential. Around the shaft, and within the cylinder. a. metallic ilange, E, is placed, for separating the parcels of grain as they enter the cylindrical screen. Y I

As the screen is rotated, the grain-is carried round, by the spiral ange E, over a space about six times as large as the number of spiral turns in the cylinder. For example, the number of spiral flanges being four in :e screen, of twofeet in length and diameter, the grain, passing four times around the cylinder, passes over a space of twentyfour feet before it is discharged through the opening a at the end. o

By means of the screens' d and cl," the 'cockle and chess are entirely separated from the sound grain, and fall to the bottom of the machine.

Upon the upper portion of the framing, and having its bearings therein, a shaft, F, is placed, parallel with the shaft B, and nearly in the same vertical plane, carrying near one end the fans Gr G, which are rotated with the shaft F by means of the beltf passing over the cylinder E and pulley e. The' fans are arranged to turn in circular openings g, formed in the top,'-iL, of the frame, and in the side ofthe frame, and a wide cross-piece, t, parallel with the side of the frame. This cross-piece is slightly cut away upon its lower edge to fit over the cylinder D. By closing the top and side around the periphery of the fans,the nir is drawn through the` latter' by their revolutions, and a stronger draught created.

The hopper H is placed upon the top of 'the framing opposite the fans, and beneath it the riddle K is suspended by means of the rods A shaking-motion is imparted to it by suitable means from the shaft F. In the drawings, a crank-connection is shown for this purpose Beneath the riddle, the inclined spoutIis placcd, connecting with' the spout J, which conducts the grain tothe interior of the cylindrical screen D.

The operation is as follows The grainis poured into the hopper, and is discharged upon the'ritldle, the

shaking of which separates the grain from all coarser matters. At the same time the dust and lighter particles' are blown out through the 'side of-the frame atK by thefans. The grain thus cleaned falls through the riddle,

and is conducted by the spouts I J to the interior of the cylindrical screen, where the cockie and chess are removed by the screens d d', andthe sound grain carried along by the spiral flange E, and discharged, thoroughly cleaned, through the opening a in the outer end vof the cylinder.'

By this arrangement the grain is entirely freed from foreign s ubstimces in a very expeditious a manner.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

v1. The arrangement ofl the fans G, riddle K, and compound cylindrical screen D, substantially as described for the purpose specified. i

2. The construction 'and arrangement of the fans G, riddle K, spouts I J, compound cylindrical screen D,

and shafts B F, substantially as described for the purpose specified. i
